Web6 jul. 2014 · The parallel garbage collector uses multiple threads to perform the young generation garbage collection. This collector should be used when a lot of work need to be done and long pauses are acceptable i am not sure which collector is used for tenured space collection by Parallel GC? Once the unreachable set has been determined, the garbage collector may simply release the unreachable objects and leave everything else as it is, or it may copy some or all of the reachable objects into a new area of memory, updating all references to those objects as needed. These are called "non-moving" and "moving" (or, alternatively, "non-compacting" and "compacting") garbage collectors, respectively. halo mcc custom games file share

The downside of this approach is an increased GC pause duration as we need to copy all objects to a new place and to update all references to such objects.
